About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: One '=' character is added when the input length modulo 3 equals 2. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
i	01101001
s	01110011
t	01110100
a	01100001
n	01101110
b	01100010
u	01110101
l	01101100

Step 2: Group Bits into 6-bit Chunks

The binary string is grouped into 6-bit chunks for Base64 encoding:

011010 010111 001101 110100 011000 010110 111001 100010 011101 010110 1100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
010111	X
001101	N
110100	0
011000	Y
010110	W
111001	5
100010	i
011101	d
010110	W
1100	w

When combined, these characters form the encoded string: "aXN0YW5idWw="
